Safety notes
Domestic travel (no State Dept advisory)
- Winter swells (Nov–Mar) make north- and west-facing shores dangerous; summer swells hit south shores.
- Shorebreak and rip currents cause most visitor injuries: swim at lifeguarded beaches.
- Hawaiʻi bans sunscreens with oxybenzone and octinoxate.
- Stay 50 ft from monk seals and 10 ft from sea turtles.
- North shore (Hanalei, Princeville) is calm in summer and dangerous in winter; Poʻipū is the reverse.
- Flash floods close the Kūhiō Highway and Nā Pali trails after heavy rain.
Check official advisories and local flags before swimming. Decomposing sargassum releases hydrogen sulfide; avoid heavy piles.
